SOR, Inc. Over Six Decades of Excellence

Logo Recently, a leading integrated energy company requested a special product for wellhead pump control and shutdown. The company needed special customized features particularly, a 4-20mA signal to serve as the primary input for a pumping unit and a solid state switch output as an emergency fail-safe device. The company also requested a flush diaphragm seal to reduce cleaning operations due to paraffin wax build-up in the pump lines. SOR installed a new custom ½” NPT (M) flush diaphragm seal system.

SOR developed an electronic pressure switch that required minimal adjustment to meet the company’s needs. The 805QS Electronic Pressure Switch uses a “window” switch operation that closes when the pressure ranges between the minimum and maximum pressure set points. The switch will open when the pressure is higher or lower than the set pressure range. Also, the switch will open if power is lost or if the unit becomes inoperative, indicating a fault condition. With just a little extra tweaking, the 805QS electronic pressure switch was the perfect solution for the energy company.
